In the far West, and in the wilds of Maine, are acres upon acres, and miles upon miles, of evergreen forests. One wooded tract in Maine is so vast that it takes an army of choppers twenty years to cut it over. By the time it is done a new growth has sprung up, and an intermediate one is large enough to cut; so the chopping goes on year after year. The first or primeval growth is pine. That is most valuable. After the pines are cut, spruce and hemlock spring up and grow. Most of the men who live in the vicinity of the lake region work in the woods in the winter. They camp in tents and log huts near the tracts where they are felling trees. All day long, day after day, week after week, they chop down such trees as are large enough to cut, lop off the branches and haul the logs to the nearest water. This work is done in winter because the logs are more easily managed over snow and ice. All brooks large enough to carry them, all rivers, ponds and lakes, are pressed into service and made to convey the ponderous freight towards civilization. All along the shores and in the woods are busy scenes--men, oxen and horses hard at work, the smoke from the logging camps curling among the trees. Every log has the initial or mark of the owner chopped deep into the wood to identify it. Then, when the ice breaks up, the logs are sent down the brooks to the rivers and through the rivers to the lakes. The logging camps are disbanded, the loggers return to their homes, and the river-drivers alone are left to begin their duties. The river-drivers are the men who travel with the logs from the beginning of their journey till they are surrendered to the saw-mills. Each wears shoes the soles of which are thickly studded with iron brads an inch long; and each carries a long pole called a "pick-pole," which has a strong sharp-pointed iron spike in the end. This they drive into the wood, and it supports and steadies them as they spring from log to log. Their first duty is to collect "the drive." The logs which form "the drive" are packed together and held in place by a chain of guard-logs which stretches entirely around the drive, forming what is called "the boom." The guard-logs are chained together at the ends about two feet apart. The guard is always much larger than the boom of logs, so that the shape of the boom may be changed for wide or narrow waters. At the head of each boom is a raft which supports two large windlasses, each of which works an anchor. On this head-work about thirty river-drivers take up their position to direct the course of the boom. To change its position or shape, ten of the drivers spring into a boat or bateau; one takes a paddle at the bow; eight take oars; and one, at the stern, holds the anchor. They row with quick strokes toward the spot where the anchor is to be dropped, the cable all the time unwinding from the windlass. "Let go!" shouts the foreman. Splash! goes the anchor overboard.
